Compositions to the place

Quite often, I watch various films / animated films and meet moments when the song is very, very much into the subject (sometimes it tears to tears).

Mulholland Drive & Prison Break

In these two wonderful films at a very good moment the song sounded:
Rebekah Del Río - Llorando

Futurama

At the end of one of the series a rather gruesome composition sounded, but very much into the topic:
Connie Francis - I will wait for you
')

5th element

There was a concert on a distant planet.
Performed by a blue alien

4400

In one of the first episodes there was a very good song and very much in the topic:
Ivy - Worry about you

LOST

In the bunker a very cool song on the record was recorded:
Petula Clark - Downtown



And what songs did you find very useful in the films?
